Methods for assessing resistance and threats to building structures in mining areas

The fi rst part of this research paper presents methods for assessing threats and resistance of the existing building structures to the infl uence of continuous surface deformation and mining tremors. The discussed assessment methods were used for the analysis of a large number of buildings located in the mining area, and they allowed to assess both the resistance of those buildings as well as the extent and intensity of potential mining damage. The second part demonstrates the results of the research involving a methodology that allows for a detailed assessment of dynamic resistance of a single building structure to the impact of mining tremors. This assessment is based on a comparison of the behavior of a structure when exposed to the loads from the design stage, with its response to the infl uence of the seismic combination, which takes into account mining impacts in the form of mining tremors. The paper also presents exemplary results of the conducted analyzes which evaluated dynamic resistance of an existing portal frame industrial building with a steel structure to mining tremors. Based on the adopted methodology, the direction of further research was defi ned. It will determine the criteria for detailed assessment of dynamic resistance of the existing building structures to the infl uence of mining tremors, considering the fact that these structures were designed with only the impacts of continuous surface deformation taken into account.
